Instrument overview
The company production of SWA-8000D series multi slope intelligent temperature control table (with RS485 communication module, optional, the same below), the production process in strict accordance with the European CE standard control instrument, plug-in circuit boards, chip components after welding, after low temperature aging (-20 C), high temperature aging (+75 C), conventional electricity aging, the special function of detection instrument checking, the actual load detection output control function of five procedures, so as to ensure that the product has a wide range of hardware anti-jamming, and in high or low temperature conditions, parameter critical point stability instrument advantages, long service life etc..
SWA-8000D series multi slope intelligent temperature control table can choose 1-32 temperature control procedures (0-31, per meter segment) segment temperature maximum arrival can be set after 1-9999 minutes to keep temperature control function. The main control software using instrument fuzzy expert actuarial techniques, using hyperbolic servo control method, the instrument has been established by P, I, D value of the master curve in the fast track, lock each section of the temperature set point deviation and correction; while some because the heater power is too large or too small, the fluctuation of temperature fast or slow, the rate of heat transfer coefficient is high or low, the same heating parts furnace and because of different temperature distribution and thermal effect of crosstalk "special" control environment, by activating the instrument "self-tuning" function, can quickly adjust the instrument, take a P optimization application of the new environment of the I group, D control parameters, so as to effectively suppress the large temperature overshoot and fast stabilized, to achieve the best effect of temperature control, temperature control to meet the requirements of different environments. Blast furnace temperature control system is widely used in ceramics, chemical industry, metal smelting and other mechanical equipment; also in coating machine, printing machine, film blowing machine, bottle blowing machine, cup making machine, extruder, CIS packaging machine and power generators to multi-point temperature control on PC and PLC, supporting the PC, a a remote multi-point bus intelligent temperature control system.
This series of products have passed the EU CE certification.
